How long is the interval between Bacillus Calmette-Guérin (BCG) vaccinations?
The vaccination schedule for DPT (diphtheria, pertussis, and tetanus) vaccine is not fixed, and generally requires about three inoculations between 3 and 12 months of age. If a child has any pathological issues during the vaccination period, the vaccination timing and intervals may need to be extended. For children who miss the vaccination schedule, parents should pay attention to making sure they catch up on the vaccines.
1. DPT vaccination can generally start from three months of age, with three inoculations between 3 and 12 months. The second inoculation is typically given 4-6 weeks after the first one, and then every 4-6 weeks thereafter for a total of three inoculations. This is the basic immunization schedule, and there can be a booster shot between 18 and 24 months of age.
2. Parents can choose to postpone the vaccination based on their child's condition. Some children may require postponement due to acute fever, infection, special allergies, or uncontrolled central nervous system diseases.
3. The vaccine itself is highly effective in preventing tetanus, diphtheria, and pertussis. Specifically, it can effectively prevent tetanus and diphtheria for 5-10 years and significantly reduce the incidence of pertussis.
4. In the absence of special circumstances, it is recommended to follow the scheduled immunization plan. However, parents can communicate with doctors to postpone the vaccination if necessary, but should try to ensure that their child catches up on the missed vaccinations.
